Does anyone else have hernias and have constant pain even after surgery?

About 3 years ago I had four hernias repaired. Two with staples and two with a single mesh screen stapled to the muscle. I asked the surgeon if I could still have babies prior to the surgery. She said yes and never gave any details about the problems this could cause, so I got pregnant and had a son about a year ago. Now I am constantly in pain. I can hardly get up some days, once I hurt so badly I laid on the floor and cried. (I have a high tolerance for pain.) The surgeon told me that they caught a nerve in the mesh staples and another staple on my side. She also said the screen was stapled in folded. There seems to be a new hernia on my other side too. All of this will eventually require another surgery. But I don't have insurance right now. Would the surgeon be responsible for repairing the mistakes free of charge? I don't really plan to go that route but the pain does not seem to get better. My real question is what can I do for the pain for now? I take over the counter pain relievers which does not help. The doc told me drinking water would help. I don't think it does. What can I do? My kids suffer as I can't always play with them. And I get crabby a lot from the pain and impatient with them, so I have to do something. Any thoughts?
